[libvirt] [PATCH] build: fix up some compiler flags

Matthias noted that the line: virt_aa_helper_LDFLAGS = $(WARN_CFLAGS) looks inconsistent, so I did an audit. Currently, the set of compiler warning flags passed to gcc as $CC are equally permitted as the set of linker flags passed to gcc as $LD, so there was no problem with that usage. But if we ever get in a situation where $CC and $LD treat particular flags differently, using the right variable form will make it easier. In the process, I spotted a couple of typos that were omitting useful flags, as well as specifying a -l under the wrong variable. * acinclude.m4 (LIBVIRT_COMPILE_WARNINGS): Define WARN_LDFLAGS as an alias for WARN_CFLAGS. * tools/Makefile.am (virsh_LDFLAGS): Use more canonical spelling. * proxy/Makefile.am (libvirt_proxy_LDFLAGS): Likewise. Move library... (libvirt_proxy_LDADD): ...here. * src/Makefile.am (virt_aa_helper_LDFLAGS): Use more canonical spelling of WARN_LDFLAGS. (libvirt_parthelper_LDFLAGS, libvirt_lxc_LDFLAGS): Likewise. Use correct spelling of COVERAGE_LDFLAGS.
